Hello friends I am Deepak Saini And today we will discus about the Process or how to manage them
Lets Start
Process:-When ever you run a command then a process run.process length is depend on command for how long it would be executed.
Three ways to check process through CLi :-
1 Ps
2 PS tree
3 top
In GUI mod We are check the process
Application -----> System Monitor -------->Process
Very first process "init" process in the linux .It PID is 1 .this process called parent process if linux init stop or kill our system is off.
PID :- PID stands for process id each process gets an uniqe when starts called its PID.
PPID :- [Parent process id ] When any process is initialize by other process so initial process become parent process id,become ppid the initialize process ae called child process.
The conditions of the process
1 R = Runing state
2 S = Sleeping uninterruptble
3 Ss = Interupible Sleep
4 sR = Sleeping but can be runn any time when required
5 Z = zombie process (when child process is killed or stope but parent process assumeing its running this state is called zombie.)
Lets start
1 How to see all current running process.
syntax:- ps
2 How to see system process
syntax:- ps -au
3 How to see all system or current process
syntax:- ps -aux
4 How to see the parent or child process like a tree
syntax:- pstree
Top is also a command to see the all process of a system .
syntax: top
In this command autoupdate after few sec .
